Abstract (en)
[origin: WO2011050383A2] The invention relates to a method for determining the orientation of an upper part (1) of a stack (2) of piece goods, in particular of a stack of metal sheets. An image of the upper cover layer of the stack (2) of piece goods is acquired by an image acquisition device (6), and a relative orientation of the upper cover layer is determined therefrom by an image evaluation module. One image (15, 16) each of a first (7) and a second (8) position of the stack (2) of piece goods is acquired, and an image analysis is performed for each image (15, 16) by an image analysis and comparison module (13). A contour (17) is extracted and a first (18) and second (19) piece of position information are determined. A distance (21) is determined from the first (18) and second (19) pieces of position information, wherein a part model (22) is created from the extracted contours (17) and the distance (21) by the image analysis and comparison module (13). The part model is compared with a stored reference model (23). If there is a deviation between the part model (22) and the reference model (23), a piece (9) of transformation information is determined.
